SPECIFICATION forming part of Letters Patent No. 788,087, dated April 25, 1905.

Application filed January 12,1905. Serial No. 240,745.

To 11// ll-lmm it HMLZ/ concern:

Be it known that I, ANTONIO Bnxnnnr'ro, a citizen of the United States, residing at \Vashington, Districtof Columbia, have invented an Improvement in Ovlinder-Jackets for Steam- Engines, of which the following is a specilieation.

My invention relates to a new form of jacket for steam-engines; and the object of my invention is to provide a means to keep a high temperature externally to the steam-cylinders and to the steam-passages in multiple-expansion vibratory steanrengines in order to prevent condensation of water in the steam-cylinders. I attain this object by the mechanism illustrated in the accompanying d rawings,

in whiclr- Figure I shows the longitudinal elevation of the jacket. Fig. 2 on the left hand side shows the side elevation and on the right hand side shows a section according to A B, Fig. l.

bimi la 1' letters refer to similar parts throughout the drawings.

The jacket consists oftwolongitudinal pipes l l, which have an interval between them and are closed at the extremities by the removable heads O. These two parallel longitudinal pipes communicate with each other by means of a series of transversal pipes p, which have a shape conforming to the periphery of the steam-cylinders of the engine in order to surround the said steam-cylinders and the steampassages. hen steam is used for heating purpose, one of the longitudinal pipes l is to be connected to the main steam-pipe by means of thejointS, leaving the other pipe I closed, and each one of these pipes is also provided with one or more openings a at the lower part of them for the steam-traps, which openings may be closed up by removable plugs 1-. \Vhen hot gases from the furnace or from other sources are used for heating purpose, the inlet S will be connected to the heating-supply and the heads O at the extremities of the other longitudinal pipe will be removed, connecting these extremities to pipes leading the hot gases to the atmosphere.

Having described my invention, what I claim is- A cylinder-jacket for a steam-engine, consisting of two parallel longitudinal pipes closed at the extremities by removable heads, said pipes separated by some interval between them and communicating with each other by means of a series of pipes having a curved shape, conforming to the periphery of the steam-cylinders of the engine, one of said longitudinal pipes provided with a joint or inlet to be connected to the main steam-pipe or to the heating-supply, and each longitudinal pipe provided at the lower part with openings for steam-traps, which openings are provided with removable plugs, substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
